Answers To Electrical Questions About Replacing A Range Receptacle With A Dryer Receptacle, Mounting Heights For Breaker Boxes and Ground Connections On Dryers

November 10, 2008

Question mark Martha asks:
I just bought a new dryer from Sears. They supplied me with a 3 prong plug (2 flat prongs, one L-shaped). My home receptacle admits 3 flat prongs. Can I replace the supplied supplied dryer cord (and cable) with an “old-style”, 3 (flat) prong plug and cable or must I install a receptacle that will accept the “2 flat, one L-shaped pin” plug?

Answer:
I usually tell everyone to replace the cord. However, in your case, I believe that you have a 50 amp range receptacle instead of a 30 amp dryer receptacle. So, I recommend replacing your 50 amp range receptacle with a 30 amp dryer receptacle. Remember to turn off the power first, this receptacle is 240 volts.

 

Ralph Connor asks:
Is their a certain height that a 200 amp breaker box must be installed from the floor?

Answer:
The National Electrical Code® (NEC®) requirement is 6 feet 6 inches maximum to the highest breaker handle above the finished floor. I typically mount mine at eye level.

 

Mona Fergerson asks:
I also have an extra green ground do I put the two green grounds together with one screw Please help me Thanks,Mona

Answer:
Essentially that is what you are going to do. However, the proper way to do this is to splice the 2 wires together with a 6 inch tail so you will only connect one wire under the screw. The NEC® only permits you to connect one wire under a screw. I believe the reason for this is to try to eliminate loose connections.

 

Kelsey Jones asks:
Hi Wayne,
Question I have a kenmore dryer the green ground wire is factory crimped together with the white neutral wire. can i disconnect only the green wire and tape it up since its crimped together with the neutral wire and then connect the new green ground wire from the 4 prong cord to the dryers ground screw?

Answer:
Yes Kelsey, this is exactly what you need to do.

    I just bought a new dryer and it has a 4 prong plug on it. 3 flat and 1 (L) shaped. My old only has 2 flat and 1 (L) shaped. I know i have to replace the plug in the wall but by replacing that, does that take care of the amp difference or do I have to change something in the fuse box as well??
